<title>Migrating from EggSMClient to GtkApplication</title>

<para>

EggSMClient provides 'session management' support for applications.
|
|
This means a number of things:
|
|
<itemizedlist>
|
|
<listitem>logout notification and negotiation</listitem>
|
|
<listitem>application state saving</listitem>
|
|
<listitem>restarting of applications with saved state</listitem>
|
|
</itemizedlist>
|
|
EggSMClient supports this functionality to varying degrees on
|
|
Windows and OS X, as well as with XSMP and D-Bus based session
|
|
managers in X11.

Starting with GTK+ 3.4, #GtkApplication supports logout notification
|
|
and negotiation similar to EggSMClient.

At this point, GtkApplication has no special support for state saving
|
|
and restarting. Applications can use GSettings or GKeyFile and save as
|
|
much state as they see fit in response to #GApplication::shutdown or
|
|
whenever they consider appropriate.
